Terminal storage is reinforced concrete circular tank, whose upper part consists of a gas-tight membrane providing a hermetic closure. As well as fermenters it is heated so raw material still fermentate there. Here is ongoing the third stage of fermentation and residual biogas is created.. Through this design, the building of terminal storage is another active fermenter called dofermenter. The storage capacity is six months, which is a significant extension of the residence time of the substrate in the process.
